Pipe supports are often used to support formwork such as beams and floors in temporary construction work for civil engineering and construction work. The structure of this pipe support is as shown in FIG. Both ends of a pin 18 inserted through the through hole 16 and pin holes 17 provided at regular intervals in the axial direction of the inner tube 15 are supported by the adjusting portion 1 engaged with the threaded portion 12. In addition, a pedestal 11 is provided at the bottom of the outer tube 13.
However, a receiving plate 14 is attached to the upper part of the inner tube 15. The support height of this pipe support is roughly adjusted by selecting the pin hole 17, and finely adjusted by rotating the adjustment tool 1.
ところで、以上のような構造から、パイプサポ

けられて係合しているねじ部12との間が堅く締
まり合う状態になる。 By the way, from the above structure, the live load supported by the pipe support is greater than the pin 18 than the inner pipe 15.
is transmitted to the outer tube 13 through the adjuster 1, and the adjuster 1 is constantly pressed with a strong force from above, resulting in a state where the screw portion 12 and the engaged threaded portion 12 are firmly tightened.

具1とねじ部12との間が一層強固に結合された
状態になる。 Furthermore, due to the working environment in which the pipe support is used, fine concrete powder, dirt, etc. may enter and accumulate on the screw part of the adjuster 1, and rust may develop on the metal surface of the screw due to long-term exposure to the rain and wind. , the adjuster 1 and the threaded portion 12 are more firmly connected.

ンマー等で何度か強い打撃を加えて、その打撃の
衝撃により堅く締まり合つたねじを回転させる方
法がとられている。 For this reason, when rotating the adjuster 1 after using the pipe support for a long period of time, especially when rotating it in the direction away from the pin 18 to loosen the screw, the gap between the adjuster 1 and the threaded part 12 will be reduced. A very large force is required to release the firmly fastened state. In such cases, it is not enough to simply operate the attached handle 2; usually, strong blows are applied several times with a hammer or the like of the adjuster 1, and the impact of the blows rotates the tightly tightened screws. A method is being taken.

具1の使用に支障をきたすという問題があつた。 However, as shown in FIG. 1, there is a handle on the protruding part of the adjuster 1 that is easy to hit with a hammer or the like and concentrates the impact, that is, on the side surface of the bracket 4 that protrudes from the outer peripheral surface of the nut 3. 2
The horizontal shaft 5 on which the adjustment tool 1 is attached protrudes, and the impact on the adjustment tool 1 will directly hit the horizontal shaft 5a. This impact causes significant damage to the horizontal shaft 5a, which causes the handle to come off, making it difficult to use the adjuster 1 thereafter.

In order to solve the above problem, this invention provides a projecting portion on the side surface of the bracket, which protrudes laterally outward from the end of the horizontal shaft that pushes the nut downward. The surface of the overhanging portion is formed to have a width equal to or greater than the diameter of the end portion, and a lateral gap is provided between the surface of the overhanging portion and the end of the horizontal shaft. .

With the above-mentioned construction, any impact applied to the pipe support adjustment tool is received by the surface of the overhanging part of the bracket, and the impact is not received by the horizontal shaft located inside. In the above-mentioned structure, the overhanging part and the end of the horizontal shaft are located close to each other, and a gap is provided between them, so that the impact can be received reliably by the surface of the overhanging part. In addition, the surface of the overhanging part is made equal to or wider than the end of the horizontal shaft, so that the overhanging part can be given sufficient strength against impact.

から保護される。 As shown in FIG. 3, the adjuster 1 is engaged with the threaded part 12 provided at the upper part of the outer pipe 13, passes through the threaded part 12 and the inner pipe 15, and protrudes from the outer periphery of the outer pipe 13. The support height of the pipe support can be adjusted by rotating the pin 18. As shown in FIG. 1, a square thread 6 is formed on the inner periphery of the nut 3, and a bracket 4 and a cylindrical projection 7 are provided at positions that protrude from the outer periphery of the nut 3 and oppose each other. The bracket 4 is formed of a pair of flat plate-like protrusions 8, and one end of the handle 2 is inserted between the protrusions 8, and is rotatably attached via a horizontal shaft 5. On the other hand, a suitable pipe or the like is attached to the cylindrical projection 7 to assist in the force for rotating the adjuster 1 together with the handle 2. The horizontal shaft 5 on which the handle is attached is fixed at both ends by large diameter portions 5a and 5b on both sides of the bracket 4, respectively, and an L shaft is formed so as to surround the large diameter portions 5a and 5b.
Letter-shaped overhangs 4a and 4b are provided. These projecting parts 4a and 4b are connected to the large diameter part 5.
It is formed to protrude outward from a and 5b and forms the outermost side of the bracket 4. The overhanging portions 4a, 4b are provided close to the large diameter portions 5a, 5b of the horizontal shaft 5, and the width of the surface thereof is the same as that of the large diameter portions 5a, 5b.
It is formed to have a diameter equal to or larger than that of 5b. Furthermore, horizontal gaps 9 and 10 are provided between the surfaces of the overhanging parts 4a and 4b and the large diameter parts 5a and 5b, so that the impact can be reliably received by the surfaces of the overhanging parts 4a and 4b. ing. (Fig. 2) As described above, in this embodiment, the large diameter portion 5a of the horizontal shaft 5 protruding from the side surface of the bracket 4,
5b, the overhanging parts 4a, 4 provided on the same side
Since the bracket 4 is positioned on the inside of the bracket 4, the blow applied to the side surface of the bracket 4 is applied to the overhanging portions 4a and 4a.
4b, and the horizontal shaft 5 is protected from the blow.

ても上記と同じ効果がえられる。 Note that the frequency at which the adjustment tool 1 is hit is mostly when the nut 3 of the adjustment tool 1 is rotated downward to loosen the screw, so only the overhanging portion 4a is provided and the larger diameter portion 5a is moved inward. By positioning the horizontal axis 5, sufficient protection can be obtained. Furthermore, the same effect as described above can be obtained by forming a groove on the side surface of the bracket 4 and providing the large diameter portions 5a and 5b of the horizontal shaft 5 at the bottom of the groove so that they are located inside the side surface of the bracket 4. available.

As explained above, in this invention, the horizontal shaft to which the handle is attached to the adjuster is positioned inward with a gap from the overhang provided on the side of the bracket, so that the impact applied to the adjuster is prevented. I decided to catch it on the overhang of the bracket, so
Damage to the transverse shaft is avoided, the handle attachment is protected, and the adjuster can be used for a long period of time.
